I have only used synthetic oil in the winter in the several SUV's I have owned over the years and always 5w30. Is there much of a cold starting difference between a 5w30 conventional oil vs a synthetic at say below zero? Has anyone here ever compared and noticed any difference?

I prefer synthetics at sub-zero temps but its been so long since I used a Dino that I couldn't offer a comparison.

I am certainly not an expert but I would say that it's below 0* F where the advantages of synthetic become apparent....

I notice a difference when it gets down below -10 F. Synthetic 5W30 seems to crank faster than dino. Years ago I put a synthetic fluid in the differential of a rear wheel drive car and I though it rolled easier at very low temps.

Not scientific but i find car to crank easier on syn in extreme cold.

Hard to say but when we had a cold snap in February a couple of years ago in the mid -20's Celsius my dino 5w30 cranked over fine. However, if my winters were consistently at or below that temperature then synthetic would be my choice.

By "below zero", I assume you mean Fahrenheit, not Celsius. 0 deg F = -18 deg C. We Americans seem to be the only ones on this forum who still use F.
Your freezer is about zero deg F, so put some in there and pour to compare. I think a dino would be noticeably thicker due to more waxy stuff in it.

Cold Comparison:

I did this a few years ago when I finally went 100% synthetic:

- 2 identical paper cups - 1 with 5W30 Dino the other with 5W30 100% synthetic same amount in both
- stick 'em both in the freezer for 2 hours (side by side for identical temps)
- take 'em out tilt the cups over 45 degrees and see how they flow
- results: 100% synthetic flowed freely! Dino oil was almost as thick as molasses! Figure it was 3-4x thicker!

More scientific method is use a Viscosity meter to measure the samples.

In Car:

In car you don't get to do a side by side comparison of Dino and Synthetic oil cold start for obvious practical reasons.
But you can notice a quicker turn over if all other factors are the same, ie battery not weak, etc.
For me, quick starts and obviously lower wear during starting with oil at the bearings as fast as
it would in the summer is a plus!

Here's a Youtube comparison at -6F. The tester didn't find much difference.

Unbelievable. Like you could qualify a statement like this..........

The very reason synthetic motor oils were invented in the first place is because the US army wanted a motor oil that would not turn to concrete for the vehicles operating at bases in the Arctic in Alaska and such, the colder it gets the more pronounced the difference between synthetic and dino gets, at 0C ( 32F ) the difference is very small, either a 5W-30 Dino or a 5W-30 Synthetic oil will flow more than adequately.
At -40 though the difference will be more pronounced, as it gets colder and colder the waxes in mineral oils thicken considerably more.

When the temps dip below -10, I'll only use synthetic underwear. It helps me flow a little faster
